Why You Need This Battery
Your NETGEAR Nighthawk M1 or M2 mobile hotspot is your lifeline to the internet when youre on the road, at a job site, or traveling abroad. When the original battery starts to fail shorter runtime, unexpected shutdowns, or no longer holding a charge your connectivity suffers. Replacing it with a cheap, low-quality battery often leads to false capacity readings, swelling, or failure within months.
